2 (12-8x) = x - 11x
24-16x = -10x (multiplied 2 by both on left, subtracted the x's on right)
24=6x (added 16x to both sides)
4=x (divided both sides by 6)

x=4.
Steps:
1. multiply 2 and 12 becuase of the distributive property. so you get 24.
2. multiply 2 and -8x to get -16x using the same property.
3. you have 24-16x=x-11x. So you combine like terms on the same sides to get 24-16x=-10x
4. add 16x to both sides to get 24=6x.
5. divide 24 by 6 to get 4=x.

2 (12-8x) = x - 11x, now multiply the left side through by 2
24 - 16x = x - 11x, now move all the x's to the right side
24 = 16x + x - 11x, collect the x's together
24 = 17x - 11x
24 = 6x, now divide both sides by 6
4 = x

2(12-8x) = x - 11 x
Eliminate brackets
24 - 16x = x - 11x
24 = x - 11x + 16x
24 = 6x
24/6 = x
4 = x

2(12-8x) = x-11x
24-16x = -10x
24-16x+16x = -10x+16x
24=6x
6x = 24
x=4

2(12-8x)=x-11x
24-16x=x-11x
24= -10x+16x
24=6x
x=24/6
x=4

1. simplify the parenthasis
24-16x = x-11x
2. move all x's to left and numbers to right
note signs of each item will change when moved from one side to the other.
-16x -x +11x = -24
3. simplify each side by adding algebricaly.
-6x = -24
4 devide each side by -6
-6x / -6 = -24/-6
x=4

2 (12 -8x)........................... = x- 11x
(2 times 12) + (2 times -8x) = x -11x
24+ (negative)16x................ = (negative)10x
------Add 16x to both sides------
+16x..................................... = +16x
24......................................... = 6x
------Divide both sides by six------
4........................................... = x
Do you understand? You have to multiply the 2 to the 12 and the (negitive)8x, to get 24 + (negative)16x = x - 11x. Then x -11x turns out to be (negative)10x. Add 16x to both sides which is then 24 = 6x. Divide both sides by six, and x = 4! ( the dots are just to make seeing things easier, they arn't for anything else.)
